Delta Air Lines passengers on a scheduled service between Paris Charles De Gaulle Airport (CDG) and Seattle-Tacoma International Airport (SEA) unexpectedly ended up in London Heathrow Airport (LHR) after the Airbus A330-900 they were on was forced to stop in the British capital due to a mechanical issue with an onboard lavatory. This left passengers stranded in London for hours and forced the pilots to declare an emergency for landing overweight.
With 209 passengers and 13 crew members onboard, the plane approached Heathrow and declared an emergency with local authorities, as it would be landing overweight. The A330 landed safely, and Delta maintenance teams were able to inspect and address the issue before it continued to its final destination on the US West Coast.
DL81 Diverted To London Due To A Leaking Toilet
Initial reports suggested that Delta Flight 81 was forced to divert after one of the lavatories onboard began leaking into the cabin. London Heathrow was the chosen diversion point, as Delta has technical crew on the ground there who could attend to the lavatory and complete a repair.
Delta quickly took action and re-routed the flight to London Heathrow, where it was able to land safely despite being overweight. The Atlanta-based carrier apologized to all passengers for the unexpected delay in a statement, noting that this was not the experience it strives to provide. Simple Flying reached out to Delta for a full statement, and received the following from an airline spokesperson:
“We apologize to our customers for their experience and delay on Delta Flight 81 from Paris-Charles de Gaulle to Seattle, which diverted to London Heathrow after the crew reported a mechanical issue involving an onboard lavatory. This is not the experience we strive to provide, and we’re focused on getting our customers to their destinations as quickly and safely as possible.”
Second Diversion Required Due To Crew Time Limits
DL81, which had departed from Paris on August 13, had an initial departure time of 4:00 PM. The flight, operated by aircraft N410DZ, was marginally delayed on its departure from the French capital and was eventually pushed back from the gate at 4:30 PM. The aircraft quickly rose to its cruising altitude of 35,000 feet and was above the skies of Birmingham before the plane turned around and headed for London after two hours and 14 minutes in the sky.
The aircraft arrived safely in London at 5:09 PM local time, where Delta maintenance crew were able to attend to the leaking lavatory, and passengers were stuck for close to two hours before the aircraft was safe to fly. DL81 eventually departed from London at 6:44 PM, and as a result of the delay, the flight was forced to once again divert due to crew time limits.
After an eight-hour, 37-minute flight across the North Atlantic Ocean, the plane diverted to New York JFK Airport (JFK), landing at 10:21 PM local time, where the crew was swapped out. This resulted in passengers being stranded once again, but passengers were able to clear customs before the flight departed as a domestic service at 1:11 AM on the morning of Friday, August 14. The flight eventually arrived in Seattle at 4:12 AM, well behind its scheduled arrival time had the flight operated without incident, of 5:34 PM.
A sewage leak and crew hour limits contributed to the flight’s late arrival.
The plane involved in the incident is five-year-old N410DZ. This aircraft was first delivered to Delta in June 2021, and is one of 39 A330-900s in the airline’s widebody fleet. N410DZ took its first test flight under French Airbus registration F-WWCR on April 2, 2021, before being delivered to Delta through a lease from Air Lease Corporation, where it was registered as N410DZ on June 15 that same year. Further aircraft characteristics below, as per ch-aviation:
After its double stopover from Europe to Seattle, the aircraft has since returned to service and overnight operated to Paris once again, this time without incident, and was marginally behind schedule, with a 90-minute delay.
